The relative diameters of the outside'of the linllrical portion of the bottom and the in UTfiBl' to place the bottom niember in the oylinilrienl hotly in proper position, consialerobleiorce must be exerted or in other .J the ports are initially united by a jriving lit, the knife like edge 7' scraping along;- the interior well of the body-end maintzi'toing' its close iii; therewith,v As above itecl, the flush seam 3 of the can body rel'ting}; from the welding of the meeting ocmon just described, there being" no shoulder or recess along the seem which would int-eriere' with o cont iuity of the close contoot more (i she entire circuit of the edge 7", serge it being sharp and terminating in the plane of the outer face of the upstench sitle of the bottom member preliZS construction which lends itself reach ily to the formation initially of a close fitting joint between the inner Wall of the body nui l the b if it attempted to make bottom w i portion, it beingimpossible to preven a slight rouinling of this corner in the chess, and a round corner will make crevice for the loigment of some of the cens contents therein, and clei ezit lhe objeci of this in vention;

om member, which can not be square iere it oins its side inside of the borly'olt' the can are such that es contributes to the initial sissembling Should any minute crevices exist between the sharp edge 7 and the Wall of the body due to slight irregularities these can be taken care of by subsequent treatment. Ordinarily these minute crevices will be closed by the tin coating but the closeness of the joint may be assured by the subsequent action just referred to. For instance in affixing the bottom to the body the flange 5 is turned up and pressed against the outside of the. body after the bottom has been thrust into the body with the driving fit mentioned,

and in this pressing 'actionthe body ,will be subjected to pressure on its exterior substantially opposite the point where the edge 7 lies so that the body will be trued up and forced in against the upstanding side of the bottom and against the edge '7' to close any crevices that may exist. This external sure may however be exerted by suitable means employed in addition tothe flange setting means, and in a different operation if desired.

The flange 5 when pressed against the side of the body will be spot welded thereto.

If desired the sharp finlike edge 7 may be treated locally by a tool inserted. into the c n1 after the bottom is placed in position, said tool being adapted to spin. roll, stamp or press the edge over to insure close contact with the Wall ofthe body;

This spinning or other actionwhich may at the same time grind the edge to facilitate its slight deformation to secure the close fit, will take care of any irregularity in the fit oi? the sharp edge of the bottom within the body, it being understood that the size and shape or the body well as of the bottom is subject to slight variation in a mechanical job of this character.

By this form of bottom with its sharp edge 7 the joint will be of a close character initially and may not need the tool work thereon. or the pressing in of the body or it so, only at certain points and the joint will be such that the tinningz operation will cover it and present a snlooth surface on which none of thecontents will lodge in such man ner as to remain after the can .issubjected' to the ordinary cleaning process.

No solder will be necessary at any point and hence the MI} when the tinning has worn oil, is susceptible of being; retinned without any preliminary operation of removing solder.

The lid of the can is formed with ii slightly flared lower edge to facilitate Cell 1 seems tering of the lid in place and also to form substantially a corrugated side to resist the hard usage to which the lid is subjected.

This lid. presents a sanitary structure because the slight fiare of its lower edge will shed dirt and liquid while adding to the strength of the lid. The flange 5 is beveled off at its upper edge 5 to shed dirt and also to prevent dislodgment of an oi the ice pack when the can is withdrawn from the freezer or case in which it is held, surrounded by the freezing, material, so that one can, when removed, will leave a smooth walled socket in the freezing material into which another can may be inserted and fit accurately without necessitating clearing away any displaced material.

The handle of the lid is formed with a sharp turn at o where its main part connects with'its pad I) so that no crevice will exist here for lodginent of dirt or refuse. The pad I) is welded to the lid. 1

l The welded side seam of the body also contributes to the sanitary character of the can.

The invention can be used as a mill: can. .ice can or for other kinds of material.

I claim:

1. A container comprising aibody portion, and a bottom having a depressed main part and a doubled back portion forming a downwardly extending vertical flange with a tinlike edge at the junction of and braced by the convergent depressed main part and doubled back portion and lying, with its highest point against the inner side of the body to provide a smooth continuous surface at the joint and a tin coating applied molten and covering said joint at the i-i'iner side of said body and bottom, said joint being solderless substantially as described. 2. A container crmiprisiug, a metal body and a bottonn the latter having a vertical face lreariireagainst the inner side of the body, said bottom being concave-convex in form with its upwardly directed concave face continued substantially unit'ori'nly to the vertical plane of said vertical face torming a fin-like edge at the junction of said concave face. whereby a lush joint is made between the body and bottom. aid joint being solderless. and a tin coating: applied unolten to the body and bottom and covering said joint.

in testimony whereof. I al'lix my signature.
